In the gallery 4-up pages and single image pages, you may use the left and right cursor keys on your keyboard
or touchscreen "swipe" right / left for much faster navigation than clicking the "next" and "previous" links.

Also note that image galleries "shuffle" their image order once per day.
If you wish to bookmark a particular image for future reference or to send to someone else,
use the "image permalink" hyperlink ( ) and make a bookmark to that page, not to a particular gallery page.

The plus ( ) and double-plus ( ) icons bring up a large jpeg and full-sized jpeg in a new window.
